MAP16: The Alien Shrine (Perdition's Gate)

MAP16: The Alien Shrine is the sixteenth map of Perdition's Gate. It was designed by Tom and Bob Mustaine and uses the music track "Delta Area" by an unknown composer.

Essentials
At the start, go around the structure in front to find the exit to this room in the opposite corner. Turn left, then go up the stairs to the left and follow the path again to your left to reach a grassy area. Turn right at the bottom of the stairs then climb both steps of stairs to the right to collect the red key and flip the switch in front. Return to the hallway after the starting area, face right at the bottom of the stairs and go through the opening on the left.

Climb up the stairs ahead and jump to the platform to the west. Follow the path until you see a red door in front. Open it, press the switch ahead then exit this room and go to the right. Approach the closest structure in front then jump to it. Continue jumping from structure to structure then follow the path to a switch. Use it then drop down to the right and enter the opening on the right to arrive at the hallway after the starting room. Go to the right then take either opening to the sides to arrive at an outside area. Go up the stairs to the south, then cross the bridge leading to the north and enter the exit teleporter to end the level.

Secrets

 * 1) After climbing the stairs northeast of the hallway after the starting area, continue walking south until you spot a detached wall to your right (west). Press it, then go down the stairs to find a megasphere. Press the grey wall in the northwestern corner at the bottom of the stairs, then go through it to arrive back in the hallway and register the secret. (sector 167)
 * 2) In the area where you jump from one watchtower to another (southwestern area), go down the stairs on the western side, then continue walking forward while hugging the wall to your right until you reach a supercharge. Grabbing this item will open a wall on the opposite corner of the bottom part of the area. There, you will find a teleporter. Use it to end up in the area near the starting one, containing a backpack, another supercharge, a BFG9000, and a megaarmor. (sector 199) Using the teleporter here will take you back to the starting area.
